SPA9000 Architecture
Multicast Addressing and Group Paging
The parameter on the PBX Parameters page defines the multicast address used by
the SPA9000 and the SPA900 Series phones to communicate with each other. The default value is
224.168.168.168:6061. This address can also be set using the IVR option 181 and reviewed using option
180.
The parameter is used by the SPA9000 for group paging of all active client
stations. The default value is 224.168.168.168:34567.
The SPA9000 can send the following messages to the phone group:
• Graceful Reboot
• Immediate Reboot
• Graceful Restart
• Immediate Restart
• Group Page Start
• Group Page End
• Get Ringing Calls
Client stations send multicast messages to the SPA9000 when they are looking for the configuration
server.
Internal music source Streams audio files to client stations (both on-net
and off-net).
The FXS1 and FXS2 can optionally be connected
to an external music source to act as a streaming
audio server (SAS). When working in this mode,
each FXS port can handle up to 10 concurrent
calls.
Administration web server Allows configuration and monitoring of the
SPA9000.

to the internal proxy server.

parked and can handle up to 10 calls
simultaneously
